Thousands of people lined a parade route Saturday as Harley-Davidson riders from around the world revved their engines, waved flags and threw candy to the crowd for the iconic motorcycle company's 105th anniversary. About 7,500 motorcycles sparkled in the sunshine as they growled along the 7.2-kilometer route by Lake Michigan. Vannettsa Valentine of Milwaukee watched the parade and slapped hands with many bikers. "I've lost count of where they all come from," she said. "I wanted to welcome them to Milwaukee." More than 100,000 people were expected in Milwaukee for the celebration, which included activities at the new Harley-Davidson Museum and a Saturday night performance by Bruce Springsteen and the E Street Band. Harley-Davidson Inc. spokesman Jerry Gleason said the riders were randomly selected from among people who bought celebration tickets before December.
